Total Cross Section of the Process e+e- -> pi+pi-pi+pi- in the C.M.Energy Range 980-1380 MeV


الملخص بالإنكليزية

The e+e- -> pi+pi-pi+pi- cross section has been measured using 5.8/pb of integrated luminosity collected with the CMD-2 detector at the VEPP-2M collider. Analysis of the data with a refined efficiency determination and use of both three- and four-track events allowed doubling of a data sample and reduction of systematic errors to 5-7%.
